Coolant: Service and Repair
ENGINE COOLANT
REPLACEMENT
1. DRAIN ENGINE COOLANT
a. Remove the water outlet cap from the water outlet.
CAUTION: To avoid the danger of being burned, do not remove the water outlet cap while the engine and radiator are still hot.
Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
b. Loosen the radiator drain plug and 2 drain cock plugs, then drain the coolant.
c. Close the radiator drain plug.
d. Tighten the 2 drain cock plugs.
Torque: 13 Nm (130 kgf-cm, 9 ft. lbs.)
2. ADD ENGINE COOLANT
a. Slowly fill the cooling system with coolant.
Capacity: 9.2 liters (9.7 US qts, 8.1 Imp. qts)
HINT:
-
Use of improper coolants may damage the engine cooling system.
-
Use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, nonamine, non-nitrite, and non-borate
coolant with long-life hybrid organic acid technology.
-
New Toyota vehicles are filled with Toyota Super Long Life Coolant (color is pink, premixed ethyleneglycol concentration is
approximately 50% and freezing temperature is -35°C (-31°F)). When replacing the coolant, Toyota Super Long Life Coolant is
recommended. Follow manufacturer's directions on label to mix.
-
ethylene-glycol (but not more than 70 %) is recommended.
b. NOTICE: Do not use alcohol type antifreeze or plain water alone.
c. DO NOT FURTHER DILUTE PRE-MIXED MANUFACTURER APPROVED ETHYLENE GLYCOL BASED COOLANT IF
USED.
-
Observe the coolant level inside the radiator by pressing the inlet and outlet radiator hoses several times by hand. If the coolant level goes
down, add the coolant.
3. CHECK FOR ENGINE COOLANT LEAKS
a. Fill the radiator with coolant, then attach a radiator cap tester.
b. Pump it to 118 kPa (1.2 kgf/cm2 17.1 psi), then check for leakage.
